OPERATING VlllCI-IANISMI FOR SUNSHDES AND THE LIKE.

Application filed October 8, 1923.

To all whom t may @0f/were:

Be it known that, l, Gnonon N. lflniN, a citizen ot the United States, residing at the city and county ot San Francisco and State ot' California. have inventedcertain new and useiiul lmprovements in @peratne' Mechanism tor Sunshades and the like. o t which the following is a specification.

This present invention relates to an operating means tor adjusting members ot different types such as awnings, vehicle windshields or sunshades; in tact. any body which it is desired to roll or which is mounted tor pivotal adjustment.

The invention consists in providing' at least two members one mounted for axial rotation and held 'from longitudinal movement. and the other held from axial rotation and mounted .tor longitudinal n'iovement. the members being interconnected by an operating pin engainnP with the axially rotatable member through a slot disposed ohliquely to its axis ot rotatioi'i` the member to he operated either adapted tor winding; around the rotating,` member or secured at one edge thereto to extend radially theretrom; the longitudinal movement of the member capable ot this operation imparting axial rotation to the other member.

The embodiment illustrated comprises a compact installation consisting of three nested rods. the outer adapted 'for axial rotation and held 'trom longitudinal movement and provided with oblique slots.r the nest innermost being` held from longitudinal movement and axial rotation and provided with longitudinal guide slots and the innermost or operating member adapted tor lon- `g'itudinal movement and provided with operatinn` pins tor extending' through the slots ot the other two respective rods whereby on the operation of the innermost member axial rotation will be imparted to the outer member to cause any part carried thereb)T to move therewith.

With the above mentioned and other objects in view. the invention consists in the novel construction and combination ot parts hereinafter' described. illustrated in the accompanying drawings. and set torth Ain the claims hereto appended, it being' understood that various changes in the form, proportion, size and minor details of construction within the scope ot the claims may be resorted to without departing from the spirit Serial No. 667,180.

or sacrilioing any ot the advantages of the invention.

ln the drawings, lfig. l is a view in plan of one embodiment o't' my invention the same illusrating its adaptation to an adiustment tor vehicle sunshades.

2 is a view in rear elevation.

Fin'. El is a view taken on line 3 3 o'li Fig.

Fig'. 4 is a longitudinal sectional view` and YFig'. is a cross sectional view on line 5--5 Fig. l.

lin the embodiment illustrated l indicates a pair ol" spaced end supporting members between which is held 'trom axial rotation and from longitiidinal movement a tubular guide rod. rlhe guide rod is provided with a pair ot longitudinal align-ed `guide slots 3 into each ot which projects an operating; pin L extended laterally 'trom a longitudinallv movable operating' rod 5 positioned within the rod 2. The rod 2 is termed with a out out portion 6 through which is adapted to extend an operating' handle connected with the rod The handle 7 has a heut portion 8 enabling the recess 9 toi-med thereby to receive the top edge ot a vehicle windshield frame and admitting' of the brackets l beingpositioned at a point below the upper edge ot the trame. to admit ot a vehicle top to lie in close proximity to the upper edge of the shield. Surrounding the supporting` rod 2 between the members l which hold the same trom longitudinal movement is an axially rotatably tubular rod l0. ln the illustration this rod is connected as at 1l with one edge of a sunshade l2 disposed longitudinally thereoic and extending;` radially therefrom. The rotatable rod l() is provided with a pair ot oblique channels 13 therein extending across the channels and 'into these channels 13 also extend the pin 4.

The device beingr assembled as 'in the drawing' the illustrated embodiment operates in the following; manner` The handle 7 extending rearwardly oi the vehicle windshield and at right angles approximately midway of its upper edge is grasped by the vehicle operator and a movement is imparted thereto to cause the operating; rod 5 to move .longitudinally of the guide 2. This movement causes the pins 4 guided in the slots 3 to bear against the edges of the slots and. cause axial movement to be .imparted to the outer tube l0 which will cause a lill raising or lowering of the free edge of the sunshade 12.

While I have illustrated this one embodiment and have shown the same as being adapted for association with the vehicle windshield it is tobe understood `that other ine-ans than the handle 7 may be employed for imparting longitudinal movement to the tube 5 and also that in place of a sunshade l2 a flexible member or awning could besecured to the outer tube l0.

l. In combination with a tubular rod supported at its ends for axial rotation and held 'from longitudinal inovelment said rod provided with a slot disposed obliquely to its axis of rotation, a member movable longitudinally within the rod and cooperating with the rod and held from axial rotation,

l, a pin oarried by said member and receivable in said slot, mea-ns for moving said member at least two of which are tubular, one oit' superimposed slots arranged at an angle to longitudinally to impart axial rotation to the rod, and a sunshade extending radially trom said rod and secured yat one edge thereto.

2. ln combination with three nested rods,

the latter being held from axial rotation and the other mounted for tree axial rotation and held from. longitudinal movement, said tubular rods being provided with disposed in angular superimposed cooperating relation, the third rod being longitudinally movableandprovided, with a. pin

projecting upwardly through said slots, means engaging the third rod for imparting reciprocating movementgthereto and extending through said cut away portions, and a suns'h ade secured atone edge 'to and extending radially from, the axially rotatable rod.

Il; In combination with three nested rods, at least two of which are tubular, one of the latter being held from axial rotatien` andthe other beingfree for axial 'rotation and held from longitudinal` movement, said tubular rods provided with slots' disposed insuperiniposed relation, the slot` of the axially rotatable rod being disposed at a right angle to its axis, and the slotof'th'e fixedro'd being parallel with4 its: axis, the innermost rod being longitudinally movable and provided withna' pinl for extending into said slots, means for' moving the innermost rod longitudinally, and a sunshade, associated with the axially`7 rotatablerodQ Y In combination withl three nested rods,

at least two which `are tubular, oneI oitY the latter beingv held from axial rotation `and the other being ireeior raxial(rotation and held trom longitudinal movement, said tubular rods provided with registering cutaway portions and 4 further provided. with slots disposed in sinn-iriiiiposecl relation, the, slototv the axially'rotatable rodbeing disposed ata right Aangle to its axis,4 andfthe slot oi: the fixedvrod being parallel with its axis, the innermostrod bein longitudinally movable and providedrwithavpin'foi extending into said slots, means for moving the inner-V most rod longitndinally anda vsiiiisliade Securedat one vedge, to the axiall-vz rotatable rod I and extending radiallyk therefrom-` In testimonyfwhe-r, I4 have signedinv naine to this specification.
